' or near the angle bar, or other splice member used for making the joint, so as to minimize the danger of the wire becoming broken or pulled from its attachments to the rails.

The principal object of my invention is to provide an improved bond wire supporter which, besides being simple and inexpensive to manufacture, will hold the wire up against the splice bar in such a way that the detachment of the same accidentally or intentionally is made impossible without removing the supporter from the splice bar.

It will be understood that the form of the device of my invention is subject to variation, depending upon the intended position of the device on the rail splicing member and the means employed for attaching it to such member. In the accompanying drawing, however, I have shown the invention in a typical or illustrative embodiment, the invention not being limited, however, to this particular form except as to certain of the claims appended hereto which are specifically so limited.

Referring to the drawing,

Fig. l is a view, in perspective, of a bond wire supporter, made .in accordance with my invention, shown as applied to an angle bar used for splicing adjacent rails.

Fig. 2 shows the blank from which the bond wire supporter is formed.

Fig. 3 is an edge view of the device.

Fig. 4: is a side elevation thereof, and

Fig. 5 is a view of the device in perspective.

Referring to the drawing, designates a railroad rail which is spliced to the adjacent rail (not shown) by angle bars 11, 11. 12

Serial No. 449,893.

is a wire used for bonding the two rails, the wire being shown fragmentarily.

The bond wire supporter is formed pref erably of a single piece of metal cut to the configuration shown in Fig. 2. That is to say,- the blank has two members 13 and 14- joined by a connecting portion 15. The member 13 is bent over on the connecting portion 15 so as to form a loop 16 adapted to extend around the bond wire 12.

The device is shown as attached to one of the angle bars 11 by means of the bolt 17 and the nut 18 used in fastening the angle bars to the rails. The inner edges of members l3 and 1d are consequently cut away, as indicated at 19, 20, for bolt 17. After the device has been slipped upon the bond wire it may be. sprung over bolt 17 if the nut 18 be loosened a trifle. When the nut is tightened the bond wire will be positively held in place against the possibility of detachment, accidently or with intention, so long as thesupporter remains attached to the angle bar. Both lugs or members of the supporter are clamped against the angle bar.

It will be understood that other means might be employed for attaching the supporter to. the angle bar such, for example,

as a separate bolt or rivet, in which case it might be desirable to change the form of the device somewhat.

I claim:

1. A bond wire supporter for attachment by a fastening device to the bar splicing abutting railroad rails composed of a substantially Z-shaped strip of metal bent to form a loop for the bond wire and to provide spaced portions which together embrace said fastening device, the ends of which loop are forced one upon the other to close the loop when the supporter is fastened to the splice bar.

2. A bond wire supporter for attachment by a fastening device to the bar splicing abutting railroad rails composed of a substantially Z-shaped resilient strip of metal bentto form a loop for the bond wire and to provide spaced portions which together embrace said fastening device, the ends of which loop stand apart to allow the bond wire to pass into the loop and are forced one upon the other to close the loop when the supporter is fastened to the splice bar.

3. A bond Wire supporter for attachment by a fastening device to the bars splicing abutting railroad rails, composed of a strip of metal having leg portions offset withrelation. to each other one of said legs being bent upon itself to form a loop for the bond Wire and to position its ends so that said legs stand on opposite sides of said fastening device and are pressed against the splice bar when the supporter is fastened to the splice bar.

4:. A bond wire supporter for attachment by a fastening device to the bar splicing abutting railroad rails composed of a strip of spring metal the ends of which are spaced apart laterally, one end of which is bent upon itself to form a loop for the bond wire, the ends of which loop stand one in front of the other to allow the bond wire to pass into the loop and stand on opposite sides of the fastening device and are pressed one toward the other to close said loop when the supporter is fastened to the splice bar.

5. A two pronged supporter for bond wires adapted to be attached by a bolt and nut to the bar splicing abutting railroad rails, composed of a strip of metal formed so that the middle portion provides a loop for the bond wires and the ends the two prongs which stand on opposite sides of said bolt and are recessed on their inner edges for engagement with the bolt, one of said prongs having a portion angularly disposed with respect to the recessed portion thereof against which the other prong is pressed to close the loop when the device is secured to the splice bar.

6. A two pronged supporter for bond wires adapted to be attached by a. bolt and nut to the bar splicing abutting railroad rails, composed of a strip of metal formed so that the middle portion provides a loop for the bond wire and the ends the two prongs which stand on opposite sides of said bolt one of said prongs having a portion angularly disposed with; respect to the portion on the side of the bolt against which the other prong is pressed to close the loop when the device is secured to the splice bar.
